Ding Ning felt that things were not simple. Liu Bin's parents had opened a shop for so many years, so they would definitely not mistake arsenic for salt. Someone must have deliberately framed it.

But Liu Bin's family is an ordinary family. Ding Ning had no idea how they provoked such people who wanted to kill others.

"Binzi, you go outside and wait for me first. I'll go find someone to ask about the situation."

"Uh-huh!"

Ding Ning turned around and walked in, came to Yu Xuan's office, and found that he was looking at some information.

"Sister Xuan?"

"Hmm?" Yu Xuan frowned slightly, responded subconsciously, then reacted again, looked at Ding Ning, and said in surprise, "Why are you here? You won't really regard this place as your workplace, right?"

"Oh! No, I just came to see you and wanted to know something from you."

"Then tell me." Yu Xuan hugged her hands and turned to look at Ding Ning.

Ding Ning told Yu Xuan about Liu Bin and finally asked, "Sister Xuan, if you are the one who took over the case, what will you do?"

"The purpose of this poisoner is very obvious, to put this family in a state of endless doom, but it is also outrageous. How could a person who has been cooking for so many years use arsenic as salt?"

"Yes! Don't say you and I don't believe it, even if you say it out, no one will believe it."

"Well...so?"

"So I suspect someone framed it. This is something that happened to my friend, so I can't ignore it!"

Yu Xuan closed the computer web page and said, "Don't worry, if the poisoned person is not in danger of his life, he will be able to get over it after compensation. But if it is really like you said to frame, the matter is not over."

"Sister Xuan is right, so can you help? It's better to take over this case!" Ding Ning said.

The reason why Ding Ning said this is because he is familiar with Yu Xuan, and he will have enough time to investigate and communicate better.

"Sorry, Ding Ning, this may not work. This case happened to be taken by the newly transferred captain. Although I can ask the inspector for this case directly, doing so is equivalent to denying the ability of the new captain. But don't worry, I'm very idle recently and can follow up."

"Okay, thank you Sister Xuan, then I'll leave first, my friend is still waiting for me outside."

"Okay, go!"

Twenty-four hours passed quickly, and Liu Bin's parents were able to leave the police room and go home, but they were not allowed to leave Huahai City.

Ding Ning wanted to investigate this matter, but he had no idea where to start. Many of the things he could investigate were taken away by the agent.

Now I can only wait until the poisoned person wakes up and find a breakthrough in his mouth.

Three days passed slowly, and Liu Bin called Ding Ning again.

Because medicinal materials that alleviate the toxicity of arsenic are very expensive, and hospitalization fees have cost nearly 500,000 yuan, almost all the money of Liu Bin's family was spent.

Liu Bin looked for Ding Ning this time to sell the copper coin he bought in the antique market that time.

Liu Bin didn't know much about this, so he could only ask Ding Ning to check it out for him.

"Okay, let's go to the antique market!"

"Xiao Ning, can we find a buyer? I actually found a few on the Internet, but I can't believe it."

Ding Ning thought for a while and said, "It's okay, let's go to the stone betting place last time to take a look! Maybe they will know where there is a place to take action on this thing."

"Uh-huh!"

Ding Ning drove Liu Bin to the antique market.

They walked to the gambling stone shop, and Ding Ning said, "Take out the copper coin first."

"Oh!" Liu Bin then took out a cloth pocket from his pocket, and the copper coin was wrapped in three layers inside and three layers outside.

"It's just a copper coin, is it necessary to wrap it so tightly?" Ding Ning said with a smile.

"This is a lot of money! Besides, what if I oxidize it, then my losses will be huge!" Liu Bin explained.

"This kind of thing has been underground for hundreds of years. Are you still afraid that it will oxidize after digging it out?"

"That's just in case!"

The two walked into the gambling stone shop, and Ding Ning walked directly to the front desk and asked, "Miss, did Boss Tang come today?"

"Oh! You guys are looking for Boss Tang! Wait for a while, I will contact him immediately. May I ask your surname?"

"Don't be ignorant, the surname is Ding, the name is Ning, and the name is Ding Ning."

"OK!"

The front desk lady immediately called Tang Jiahao. When she heard that Ding Ning was looking for him, she immediately walked out to greet him in person.

"Brother Ding Ning, long time no see!" Tang Jiahao walked over enthusiastically and shook hands with Ding Ning.

Ding Ning smiled and said, "Boss Tang, I think you look good! You must have done a good deal recently, right?"

"Hahahaha! You can see this. It's not bad. I've made a small profit. Don't stand outside. Let's talk to my room! Have a cup of tea! Have a cup of tea!"

"Then I'm not polite, Binzi, let's go!"

"Please!" said Tang Jiahao.

The three of them came to Tang Jiahao's independent hut and sat on the leather sofa. A receptionist wearing a cheongsam made tea for them.

"Well! This is the best Longjing, and the taste is indeed extraordinary!"

"I laughed at you, I laughed at you!"

"Brother Ding Ning, you haven't come recently. I thought you forgot me, the old man!" Tang Jiahao quipped.

"That's not. I'm still a student after all, I'm just here today. By the way, I'm here this time..." Ding Ning took a sip of tea and continued, "I want to ask you something."

"What's the matter? As long as I, Mr. Tang, know, I will tell you the truth."

"To be honest, something happened to my friend's family. I want to take something out. Please help me." Ding Ning asked Liu Bin to take out the copper coins and handed them to Tang Jiahao.

Tang Jiahao is not only the overlord of the stone gambling world, but also has a lot of research on antiques. The reason why Ding Ning found him was because gambling stones are also somewhat related to antiques.

Tang Jiahao took the copper coin and looked carefully. He seemed to have seen the copper coin somewhere, so he picked up the magnifying glass and started to observe it.

After a long time, Tang Jiahao said, "Brother Ding Ning, the thing you are going to take action is amazing! I only know that it is old and the price should be tens of millions, but... it needs further identification."

"I initially estimate that this copper coin should be from the Tang Dynasty." Ding Ning said lightly.

"That's amazing. There are many popular copper coins in the Tang Dynasty. This is rare and probably rare. The price is definitely only high or low."
